Dark and unordinary films

I've watched a lot of films and I've noticed that there are sometimes film that you just can't put your finger on them, all you can say is that they are dark in atmosphere, unordinary, unhollywoodlike...

If you want nihilistic, then I would suggest "Baise Moi," "Martyrs" and "Srpski film" a.k.a. "Serbian Film."

I only am suggesting them, I am not recommending them. Well, maybe "Martyrs." But definitely not "Serbian Film." "Serbian Film" is the film you use to test your morals. It has the potential to wreck you for days after you watch it. "Baise Moi" blurs the line between art, storytelling and pornography.
